Well, if the feature really is going to be something that a _normal_ 
netfilter config needs, then it should indeed be turned on.

However, nothing in the docs imply that at all. Can you explain? Why 
should IP_NF_SECURITY be on, and why should a default netfilter table 
enable it? And if it should, WHY THE HELL IS IT DOCUMENTED THAT YOU SHOULD 
SAY 'N'?

Patrick, see my original report:

That option as it stands now MAKES NO SENSE. Either you should say 'Y' 
(and you should explain _why_), or you should say 'N' (as documented) and 
it should damn well default to 'N' too!
